Yes. I own one. But the multiplier doesn't have the impact feature.
That's what the 2 pound ball peen hammer and liquid wrench are for. Soak it down with liquid wrench then hit a few times in a few different directions with the hammer. I usually use a piece of soft iron bar stock between what I'm hitting and the hammer. Also I use 50% ATF and 50% acetone rather than liquid wrench. Works better and is much cheaper. On the other hand I would never use that combo inside.
